Windows 7: Persistent 0x50 BSOD upon restart, fresh install.

22 Apr 2012   #1

Window 7 Home Premium 64 bit
Persistent 0x50 BSOD upon restart, fresh install.

Hello guys, I've got an annoying BSOD on a nearly new computer, and I've tried to exhaust possibilities but can't seem to nail it down.

Windows 7 x64 OS
AMD Athlon ii x2 250 Processor @3 ghz
Gigabyte GA-M68MT-SP2 F1 (w/ onboard Nvidia GeForce 7025/630a Graphics)
ATI Radeon HD 5400 1 GB Graphics
8GB 1333mhz PKR RAM (replaced 4GB Kingston, replaced to rule out RAM fault)
500 GB Seagate Harddisk
It's a custom build from Ginger6

The BSOD keeps occurring even on a fresh OS; I reinstalled last night and it begins happening from the first windows update restart, or sometimes when installing programs.

I've tried to rule out graphics - BSOD occurs both with ATI graphics card installed and also on the onboard Nvidia Graphics - I've used their respective online tools to find the right drivers, so I think they're up to date

I've also tried to rule out Ram faults - I tested the original kingston Ram numerous times on Memtest and Windows Memory debugging - no faults came back but to be safe I replaced with the 8GB PKR

I've ran chkdsk on the hard disk and it came back with no errors - in previous attempts I formatted the drive before a fresh OS install - no joy there

Bluescreen view points to ntoskrnl.exe, and I've tried using the MS debugging but I'm not sure I'm doing it right

So, all in all, I'm at a loss as to what to try next - I figured the experts here might be able to help me out. Thanks for your time, much appreciated

The above crash usually indicates memory problems. Also, make sure you do not have ATI and NVIDIA software installed at the same time; it can conflict and cause crashes.

The below information is to help you install the latest driver for the graphics device you are currently using, and it is also provided to help you remove the software the device you are not using.
  1. Download the latest drivers for your display card(s)
  2. Click Start Menu
  3. Click Control Panel
  4. Click Uninstall a program
  5. For NVIDIA:
    • Uninstall the NVIDIA Graphics Driver (this should uninstall all NVIDIA software and drivers)
    • Restart your computer
    • Make sure NVIDIA 3D Vision Driver, NVIDIA 3D Vision Video Player, NVIDIA HD Audio Driver, and NVIDIA PhysX System Software are not still listed under Uninstall a program through Control Panel
    • If any remain of the above, uninstall one at a time
    • If asked to restart after uninstalling any of the above, do so, and continue uninstalling any remaining NVIDIA items until all are removed
  6. For AMD:
    • Uninstall AMD Catalyst Install Manager if it is listed (this should remove all AMD graphics software and drivers)
    • If AMD Catalyst Install Manager is not listed, use the following method to uninstall the graphics drivers:
      1. Click Start Menu
      2. Right Click My Computer/Computer
      3. Click Manage
      4. Click Device Manager from the list on the left
      5. Expand Display adapters
      6. Do the following for each adapter (in case you have multiple display cards)
        • Right click the adapter
        • Click Uninstall (do not click OK in the dialog box that pops up after hitting Uninstall)
        • Put a tick in Delete driver software for this device (if this option is available, otherwise just hit OK) and hit OK
      7. Restart your computer after uninstalling drivers for all display cards
      8. Install the latest driver for the display cards once Windows starts

      1. Login as an adminstrative user
      2. Click Start Menu
      3. Click Control Panel
      4. Click Hardware and Sound
      5. Click Device Manager (the last link under Devices and Printers)
      6. Expand Display adapters
      7. Do the following for each adapter (in case you have multiple display cards)
        • Right click the adapter
        • Click Uninstall (do not click OK in the dialog box that pops up after hitting Uninstall)
        • Put a tick in Delete driver software for this device (if this option is available, otherwise just hit OK) and hit OK
  7. Restart your computer after uninstalling drivers for all display cards
  8. Install the latest driver for the display cards once Windows starts

Check your memory:
  • Run the boot version of Memtest86+ paying close attention to Parts 2 and 3 of the tutorial. Also, in case Memtest86+ misses anything and comes up with no errors, run the extended version of the Windows Memory Diagnostics Tool for at least five passes. These you may want to run overnight since they take a long time to complete (run them an hour before bed each of the next two nights and check before going to sleep that they are still running).

    For Part 3: If You Have Errors: If you swap any memory components, follow these steps for ESD safety:
    1. Shut down and turn off your computer.
    2. Unplug all power supplies to the computer (AC Power then battery for laptops, AC power for desktops)
    3. Hold down the power button for 30 seconds to close the circuit and ensure all power drains from components.
    4. Make sure you are grounded by using proper grounding techniques, i.e. work on an anti-static workbench, anti-static desk, or an anti-static pad. Hold something metallic while touching it to the anti-static surface, or use an anti-static wristband to attach to the anti-static material while working.
    Once these steps have been followed, it is safe to remove and replace components within your computer.

  • Then use the |MG| Video Memory Stress Test 1.7.116 Download to test your graphics card memory. Let the memory test run for at least seven passes; the more the better.

Hello there, cheers for replying :)
I uninstalled the Nvidia and ATI software via the control panel, and restarted, which resulted a couple more crashes, same 0x50 type: the ATI card plus drivers are still installed
Looking through the device manager, I do appear to have a mix of ATI and Nvidia drivers -

ATI Radeon HD 5400 Series
NVIDIA nForce Serial ATA Controller
NVIDIA nForce Networking Controller

The onboard motherboard graphics are also Nvidia, but those drivers are not installed at the moment.
I'm going to run without the ATI graphics card, and just on the m/board graphics, to see if it is a the ATI Nvidia conflict

edit* Right, I've taken the graphics card out and computer is running on the integrated m/board graphics only, no blue screens, and I've restarted numerous times to make sure.

Is it worth trying to re-install the ATI card? I can't find any individual drivers on their website, it all seems to come under the Catalyst software, so is there somewhere else I should be looking or would that be alright?

The mixed NVIDIA and ATI drivers will occur on your system, but you need to avoid mixed graphics drivers. The drivers you list are for your hard disk controller and network controllers and will not conflict with the graphics. What you want to make sure of is no NVIDIA graphics related software through start menu -> control panel -> uninstall a program by going through the software I provided in my previous post and making sure none of that software is installed when using the ATI card.

You should try installing only the drivers for the ATI card after uninstalling the AMD Install Manager software. You can manually install the drivers for the ATI card as follows:
  • Download the ATI Catalyst software and begin the install.

  • Start the installation.

  • When you are given the option for the express install, cancel out of the installation.

  • The ATI folder should now be unpacked in C: under the AMD folder.

  • Open device manager as in my previous post.

  • Go to Display adapters and expand it by pressing the arrow/triangle to the left of the icon. Note: Your display adapter may also show up in unknown devices with a yellow triangle and exclamation point. You may also have to click the scan for hardware changes to get it to show up. To scan for hardware changes, click on the icon showing the Magnifying glass hovering over the computer.

  • Right click the generic VGA adapter (if it already says ATI then you do not need to follow the next steps)

  • Click Update Driver Software...

  • Follow steps 3-5 in OPTION TWO of Drivers - Install Vista Drivers on Windows 7

  • The drivers will be in C:\AMD\Support\**-*_vista_win7_64_dd_ccc\Packages\Drivers\Display\W76A_INF
The asterisks are for the version of the driver being installed. Mine, for instance, were 12-3_vista_win7_64_dd_ccc\Packages\Drivers\Display\W76A_INF

Okay, problem seems fixed! Thanks for your help!

Think I might go with an Nvidia graphics card next time if it avoids all these issues.
